Diễn đàn hỗ trợ Firefox

I don't know how or why but apparently Mozilla VPN has been installed on my computer. I don't think I ever requested it as I have Express VPN and I never subscribed to it. I've attached a screenshot and I don't know what else this could mean (note: I am technologically challenged). I didn't have my Express VPN turned on at the time I took this picture.

I can't log into an email from my health site called MyMercy to get lab reports, etc., using Firefox; Have to switch to Google Chrome to do it. Is Firefox aware of this issue? Please respond [edited email from community support forum]

Why is Firefox sending me email msg's saying to try the new firefox VPN when It doesn't seem to be available to me? It's not in the upper right corner as they state and it's not in the toolbar either which they also say it's suppose to be in!

I need to udate my current version of Firefox, however, my MAC is so old that it wont run the most currnet version of Firefox. Can anyone tell me which version will run on my MAC Sierra version 10.12.6 Thank you.

I can't sign in to my Google account and chrome is my preferred browser and I am getting messages saying that I am signed in to another browser. I want to try uninstalling Firefox and hope that will allow me to get signed in to my Google account.

So I clicked into a video, and it did not play. Further troubleshooting showed it was a video hosted by vimeo, and youtube videos still worked. I tried on multiple vimeo hosted videos, on multiple unconnected websites (dropout, patreon, and directly on the vimeo website).

I tried the following fixes:

• I opened it in a private window and nothing played.
• I booted into safe mode, still nothing.
• I turned off all of my add-ons, nope.
• I cleared my cache and restarted, nothing.
• I cleared my browsing data and restarted, also nothing.
• I checked for updates: up to date.
• I created a test profile, and it works there.
• I opened Chrome and it worked there too.

The test profile/chrome thing suggests it's an add-on or something but the fact that I turned them all off and this still happened has me baffled.

I've attached console photos of the 3 error consoles from the 3 sites. I'm smart enough to know I'm very stupid when it comes to this, so any advice at all would help!

I want to view USPS PDF labels from their new API. These PDF's are version 1.7. Chrome and Edge all ready work. Will FireFox support this as well ? Viewing one of these PDF's displays a black or white screen.

I would have attached one of the labels so you can see for yourself but you only accept images.

Ask me and I will send you one.

after last update stop working .if I use ctrl v it will paste in. When i try using the mouse it doesn't have paste in the block that pops up.

I can click and paste in the condition box but not the description box.

If I use edge it works. I don't want to use edge

I have also cleared cookies and cache

When I visit a particular web site it requests that I grant Firefox access to location services. When I attempt to, the site's interface takes me to (Apple) System Settings/Privacy & Security/Location Services and shows me the access status of the Firefox.app. The control next to it shows it as off. Clicking on the control to change it to on does nothing. The web site cannot access location services.

Location Services itself is on, as are permissions for several other apps (including Safari, which does not have this problem with this web site).

Within the Firefox apps own settings, location permissions for the site in question (scistarter.org) are set as Allow.

I'm on an iMac, running Tahoe 26.5. This problem does not happen on my iPhone running iOS 26.5.

Help?

Can not find free VPN prompt in upper right hand corner in Firefox 150.0. When updating it asked if I wanted the free VPN I click yes and it took me to a page labeled "Use built-in VPN in Firefox" No icon appeared nothing.

I just bought my boyfriend a new iMac. We are having trouble loading many sites and platforms using the latest Firefox browser. The list is growing but includes Facebook, Meetup, Wikipedia, chess.com, nytimes.com - in all cases, rather than a login screen, we get an error message or a home page loads with no access to other pages or login area. I've cleared the cache, restarted, tried going directly to the site to log in, but nothing works. Everything is fine when using Chrome, but we prefer Firefox. Is this a conflict in the new Apple OS? Is there a fix?

firefox set up won't load. I have completed all of the required steps but I am still being asked to finish the set up. Anybody else have this issue? If so what do I do?

Been using Firefox for over a decade. But lately is has become so slow now. Often freezes up if more than two tabs are open or a website is in any way very complex. What settings and issues should I check? What has changed? I can run the same sites on Brave and Edge browsers with no issues or not nearly as slow and bogged down.

I downloaded the Firefox ESR for my High Siera OS, but I still get the message that Firefox is no longer supported, Why??? Just let me know what I need to do so I can use the browser without worry.

I have a MacPro 2012, updated to the max. I'm retired, and by budget does not allow for a new computer.

Thanks. Doina Paraschiv
